The date of the Closing is referred to herein as the " Closing Date ."

including payments under Management Incentive Interest Award Agreements, relating to the consummation of the transactions contemplated by this Agreement; and

(i)     the Purchaser and the Seller shall make such other deliveries as are required by Article II hereof.

1.05      Purchase Price Adjustments .

(a)     At least two business days prior to the Closing Date, the Acquired Company shall deliver to the Purchaser a good faith estimate of Net Working Capital (the " Estimated Net Working Capital "), Cash on Hand (the " Estimated Cash on Hand "), Indebtedness (the " Estimated Indebtedness "), and Company Transaction Expenses (the “ Estimated Company Transaction Expenses ”) and the resulting calculation of the Estimated Purchase Price.

(b)     As promptly as possible, but in any event within sixty days after the Closing Date, the Purchaser will deliver to the Seller a statement showing the Purchaser's calculation of Net Working Capital, Cash on Hand, Indebtedness, and Company Transaction Expenses (the " Preliminary Closing Statement "). The Preliminary Closing Statement shall be prepared in accordance with GAAP or in accordance with this Agreement if different from GAAP, applied on a basis consistent with the methods, policies, practices, procedures, classifications and estimation techniques used in the preparation of the Audited Financial Statements. The parties agree that the purpose of preparing the Preliminary Closing Statement and determining Net Working Capital, Cash on Hand, Indebtedness, and Company Transaction Expenses and the related purchase price adjustments contemplated by this Section 1.05(b) is to measure changes in Net Working Capital and the levels of Cash on Hand, Indebtedness, and Company Transaction Expenses as of Closing, and such processes are not intended to permit the introduction of different judgments, accounting methods, policies, principles, practices, procedures, classifications or estimation methodologies as those used in the preparation of the Audited Financial Statements. After delivery of the Preliminary Closing Statement, the Purchaser shall give the Seller and its accountants reasonable access to review the Purchaser's and the Company Group's books and records and work papers related to the preparation of the Preliminary Closing Statement. The Seller and its accountants may make inquiries of the Purchaser and its Subsidiaries (including the Company Group) and their respective accountants regarding questions concerning or disagreements with the Preliminary Closing Statement arising in the course of its review thereof, and the Purchaser shall, and shall cause its Subsidiaries to, cause any such accountants to cooperate with and promptly respond to such inquiries. If the Seller has any objections to the Preliminary Closing Statement, the Seller shall deliver to the Purchaser a statement setting forth its objections thereto (an " Objections Statement "). If an Objections Statement is not delivered to the Purchaser within thirty days after delivery of the Preliminary Closing Statement, the Preliminary Closing Statement shall be final, binding and non-appealable. The Seller and the Purchaser shall negotiate in good faith to resolve any such objections, but if they do not reach a final resolution within thirty days after the delivery of the Objections Statement, the Seller and the Purchaser shall submit such dispute to KPMG LLP or such other mutually acceptable dispute resolution firm (the " Dispute Resolution Firm "). Any further submissions to the Dispute Resolution Firm must be written and delivered to each party to the dispute. The Dispute Resolution Firm shall consider only those items and amounts which are identified in the Objections Statement as being items which the Seller and the Purchaser are unable to resolve. The Dispute Resolution Firm's determination will be based solely on the definitions of Net Working Capital, Cash on Hand, Indebtedness, and Company Transaction Expenses, as applicable, contained in this Agreement. The Seller and the Purchaser shall use their commercially reasonable efforts to cause the Dispute Resolution Firm to resolve all

disagreements as soon as practicable and in any event within forty-five days after the submission of any dispute. Further, the Dispute Resolution Firm's determination shall be based solely on the submissions by the Purchaser and the Seller which are in accordance with the terms and procedures set forth in this Agreement, and not on the basis of an independent review. The resolution of the dispute by the Dispute Resolution Firm shall be final, binding and non-appealable. The costs and expenses of the Dispute Resolution Firm shall be allocated based upon the percentage which the portion of the contested amount not awarded to each party bears to the amount actually contested by such party in the presentation to the Dispute Resolution Firm; however, the Seller and the Purchaser shall equally advance any costs and expenses of the Dispute Resolution Firm that are payable prior to rendering a determination. For example, if the Seller submits an Objections Statement for $1,000, and if the Purchaser contests only $500 of the amount claimed by the Seller, and if the Dispute Resolution Firm ultimately resolves the dispute by awarding the Seller $300 of the $500 contested, then the costs and expenses of the Dispute Resolution Firm will be allocated 60% ( i.e. , 300/500) to the Purchaser and 40% ( i.e. , 200/500) to the Seller.

(c)     Post-Closing Adjustment .

(i)      If the Final Purchase Price is greater than the Estimated Purchase Price, the Purchaser shall promptly (but in any event within five business days after the determination of the Final Purchase Price) deliver to the Seller the amount of such excess, by wire transfer of immediately available funds to an account or accounts designated by the Seller.

(ii)      If the Final Purchase Price is less than the Estimated Purchase Price, the Seller shall promptly (but in any event within five business days after the determination of the Final Purchase Price) deliver to the Purchaser the amount of such shortfall, by wire transfer of immediately available funds to an account designated by the Seller.

1.06      Withholding Rights . The Purchaser or its designee and the Company Group shall be entitled to withhold and deduct from the consideration otherwise payable pursuant to this Agreement such amounts as such Person is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law; provided that if the Purchaser, the Acquired Company or any of their respective Subsidiaries determines that an amount is required to be deducted and withheld, at least two business days prior to the date the applicable payment is scheduled to be made, the Purchaser shall provide the Seller with written notice of the intent to deduct and withhold, which shall include a copy of the calculation of the amount to be deducted and withheld and any applicable provision of state, local or foreign Tax law pursuant to which such deduction and withholding is required and provide the recipient of such payment a reasonable opportunity for such recipient to provide forms or other evidence that would exempt such amounts from withholding. To the extent that amounts are so withheld and paid over to the appropriate Tax authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding were made.

9.02      Indemnification from the Indemnity Escrow Account for the Benefit of the Purchaser .

(a)     From and after the Closing (but subject to the provisions of this Article IX ), the Seller and Seller Shareholder shall, jointly and severally, indemnify the Purchaser in respect of any Loss suffered or incurred by the Purchaser or any of its Affiliates, officers, directors, employees or agents (each a " Purchaser Indemnified Party " and collectively, the " Purchaser Indemnified Parties ") resulting from or arising out of (i) the breach or inaccuracy of any representation or warranty made by the Acquired Company in Article III (Representations and Warranties of the Acquired Company), by the Seller in Article IV (Representation and Warranties of the Seller), or the Seller Shareholder in Article V (Representations and Warranties of the Seller Shareholder); or (ii) the breach by the Seller or the Acquired Company of any covenant or agreement to be performed by it under this Agreement.

(c)     Amounts available in the Indemnity Escrow Account shall be the sole source of recourse against the Seller or Seller Shareholder for Losses suffered or incurred by Purchaser Indemnified Parties to the extent arising from any nonfulfillment or breach of any representation or warranty other than a Fundamental Representation. The maximum aggregate liability of Seller or the Seller Shareholder for Losses related to indemnification claims hereunder, including claims arising from any nonfulfillment or breach of any Fundamental Representation, shall not exceed the Final Purchase Price.

(d)     The Purchaser Indemnified Parties shall have no right to indemnification hereunder with respect to any Loss to the extent such Loss is included in the calculation of any component of Final Purchase Price or if the Purchaser shall have received a reduction in the Final Closing Statement on account of any matter forming the basis for such Loss.

(e)     All payments pursuant to this Article IX shall be treated by the parties as an adjustment to the proceeds payable to the Seller pursuant to Section 1.02 hereof.

As soon as the Outstanding Escrow Claims are resolved pursuant to the procedures set forth in this Article IX , the Purchaser shall cause the Escrow Agent to release any remaining cash held by the Escrow Agent pursuant to the terms of the Escrow Agreement to the Seller.

9.03      Indemnification by the Purchaser for the Benefit of the Seller . From and after the Closing (but subject to the provisions of this Article IX ), the Seller shall be entitled to assert, as its sole and exclusive remedy for any action relating (directly or indirectly) to this Agreement and the transactions contemplated hereby and only in accordance with the terms of this Agreement, claims against the Purchaser in respect of any Loss suffered or incurred by the Seller, or any of its respective Affiliates, officers, directors, employees or agents (" Seller Indemnified Parties ") to the extent arising from any nonfulfillment or breach of any representation, warranty, covenant, agreement or other provision set forth herein or in any or certificate delivered hereunder by the Purchaser or, following the Closing, by the Acquired Company.

9.04      Mitigation . Each Person entitled to indemnification hereunder shall take commercially reasonable steps to mitigate all Losses, costs and expenses as required by applicable Law.

9.05      Defense of Third Party Claims . Any Person making a claim for indemnification under Section 9.02 or Section 9.03 (an " Indemnitee ") shall notify the indemnifying party (an " Indemnitor ") of the claim in writing promptly after receiving written notice of any action, lawsuit, proceeding, investigation or other claim against it (if by a third party), describing the claim, the amount thereof (if known and quantifiable) and the basis therefor. Any Indemnitor shall, subject to the right of any insurer under a representation and warranty insurance policy, be entitled to participate in the defense of such action, lawsuit, proceeding, investigation or other claim giving rise to an Indemnitee's claim for indemnification at such Indemnitor's expense and, subject to the right of any insurer under a representation and warranty insurance policy, at such Indemnitor's option, shall be entitled to assume the defense thereof by appointing a reputable counsel to be the lead counsel in connection with such defense; provided that such Indemnitor shall continue to be entitled to assert any limitation on any claims contained herein; provided further that the Indemnitee shall be entitled to participate in the defense of such claim and to employ counsel of its choice for such purpose; provided , however , that the fees and expenses of such separate counsel shall be borne by the Indemnitee. If the Indemnitor shall control the defense of any such claim, the Indemnitor shall, subject to the right of any insurer under a representation and warranty insurance policy, be entitled to settle such claim; provided that the Indemnitor shall obtain the prior written consent of the Indemnitee (which consent shall not be unreasonably withheld, conditioned, or delayed) before entering into any settlement of a claim or ceasing to defend such claim if, pursuant to or as a result of such settlement or cessation, injunctive or other equitable relief will be imposed against the Indemnitee or if such settlement does not expressly and unconditionally release the Indemnitee from all liabilities and obligations with respect to such claim. If the Indemnitor assumes the

defense of and/or settles or compromises any third party claim as provided herein and the Deductible applies to such claim and has not been met with respect to the Indemnitor's liability under Section 9.02 , then (1) until such time as the Deductible has been met, the Indemnitee will promptly reimburse the Indemnitor for any out-of-pocket costs and expenses (including attorney's fees) incurred in the assumption of such defense and (2) if the settlement or compromise of such third party claim is equal to or less than the remaining Deductible at such time (after taking into account any reimbursements pursuant to clause (1) above), then within five business days after the settlement or compromise of such claim, the Indemnitee shall pay to the Indemnitor the aggregate amount of the third party claim settled or compromised up to the amount of the then remaining Deductible. In no event will an Indemnitee consent to the entry of any judgment or enter into any settlement with respect to any third party claim for which an Indemnitee is seeking indemnification hereunder without the prior written consent of the Indemnitor.

9.06      Determination of Loss Amount .

(a)     The amount of any Loss subject to indemnification under Section 9.02 or Section 9.03 shall be calculated net of any insurance proceeds (net of direct collection expenses) or any indemnity, contribution or other similar payment received by the Indemnitee or its Affiliates from any third party with respect thereto. The Indemnitee shall seek full recovery under all insurance policies covering any Loss to the same extent as they would if such Loss were not subject to indemnification hereunder; provided that seeking such coverage shall not be a condition to Indemnitee making a claim for indemnification under this Agreement.

The specification of any dollar amount or the inclusion of any item in the representations and warranties contained in this Agreement or the Schedules is not intended to imply that the amounts, or higher or lower amounts, or the items so included, or other items, are or are not required to be disclosed (including whether such amounts or items are required to be disclosed as material or threatened) or are within or outside of the Ordinary Course of Business, and no party shall use the fact of the setting of the amounts or the fact of the inclusion of any item in this Agreement or the Schedules in any dispute or controversy between the parties as to whether any obligation, item or matter not described or included in this Agreement or in any Schedule is or is not required to be disclosed (including whether the amount or items are required to be disclosed as material or threatened) or is within or outside of the Ordinary Course of Business for purposes of this Agreement. The information contained in this Agreement and in the Schedules hereto is disclosed solely for purposes of this Agreement, and no information contained herein or therein shall be deemed to be an admission by any party of any matter whatsoever (including any violation of law or breach of contract).

Furthermore, the Purchaser agrees, on its own behalf and on behalf of each of its Subsidiaries (including, after Closing, the Company Group), that in the event of a dispute between the Seller or any of the Seller's Affiliates, on the one hand, and the Acquired Company or any of its Subsidiaries, on the other hand, arising out of or relating to any matter in which Law Firm jointly represented both parties, neither the attorney-client privilege, nor the expectation of client confidence nor any right to any other evidentiary privilege will protect from disclosure to the Seller or such Affiliate of the Seller any information or documents developed or shared during the course of Law Firm's joint representation.

13.20      Tax Withholding on Compensatory Payments . Notwithstanding anything to the contrary in this Agreement, to the extent that an amount is paid or is payable to the Seller pursuant to this Agreement for the benefit of any service provider of the Company Group and such amount may be subject to payroll and employment tax withholding under applicable law ( e.g. , such amounts are payable by the Seller to an employee of the Company Group and those amount are treated as "wages" under Code Sections 3121, 3306, or 3402), then, at the written request and direction of the Seller, the Purchaser shall, or shall cause the applicable Member of the Company Group to, pay such amounts through the applicable payroll system of the Purchaser or the applicable Member of the Company Group and make all applicable employment and payroll tax withholding on such amounts in accordance with applicable law; provided that, if such amount has already been paid to the Seller, then the Seller agrees to promptly deliver such amount to an account designated by the Purchaser.

(b)     During the period beginning immediately following the Closing and ending on the fifth (5 ^th ) anniversary of the Closing, neither Seller nor Seller Shareholder shall control, manage, operate, be employed or engaged by, or otherwise participate or engage in any business as, or have any interest in, a Competitive Business.
